Dynamics of industrial waste stabilization pond treatment process.

Waste stabilization pond is an artificial ecosystem; its performance is governed by the nature of the biological communities it supports. These are primarily used as secondary effluent treatment plants to polish the effluents. However, they are also used to treat the raw sewage and industrial effluents.

Combined treatment of chemical, pharmaceutical and cosmetic industrial effluents by waste stabilization ponds.

Influent and final effluent was collected from the CMM Ltd., Bethora, Ponda, Goa and were analysed for pH, DO, BOD, enzyme activity and chlorophyll content of the waste stabilization pond for over a period of two years of which the data for one year (pre monsoon, monsoon and post monsoon periods) is given. The study revealed that the DO was maximum during the pre-monsoon months and least during the monsoon.
